Abstract
An article of furniture having a seat of a generally constant orientation but a back which can be tilted at various angles has a generally X-shaped relationship of the seat and back and, on each side a pair of horizontally spaced pins, affixed to the seat, one of which rides on the upper surface of a cooperating member of the back while the other can be selectively fitted into notches of a rack structure on the lower edge of the respective member. The upper edge or surface of these members have a cam configuration and the distance separating this edge from the bottoms of each of the respective notches is progressively increased downwardly along the rack so that the seat inclination is substantially constant for all positions in which the pins engage the notches.
Claims4
A seating unit comprising:
- a seat member and a back member interfitted in a generally X configuration so that a lower portion of said seat member and a lower portion of said back member form rear and front purchases for said unit on a floor, said seat member being inclined downwardly from a front thereof to its rear portion;
- and
- means for indexing said back member relative to said seat member in a plurality of selected angular positions corresponding to various inclinations of said back member while the inclination of said seat member relative to the floor is substantially constant, at least one of the sides of said back member being formed with an element extending between its lower portion and an upper portion of said back unit and formed with upper and lower edges, the corresponding side of said seat member being provided with a pair of horizontally spaced pins straddling said element, said means including a rack of notches formed along said lower edge and receiving selectively one of said pins, the other of said pins resting upon the upper edge of said element.
